Patented July 28, 1931 VICTOR F. ZAI-IODIAKIN, OF CINCINNATI; O l-IEO INTERNAL COMBUSTIO ENGII IE s'tr-ARTmG MEoH'AnIsm Application filed September 11, 1929. Serial no; 391.79%

The invention relates to means for startin or rotating internal combustion engines.

The ob ects of the invent on are to provide a simple, efiicient and practical means means whereby said frictionally engagedp parts are adapted to eliminate lost mot-ion 20 thereby transmitting said power with minimum loss resulting from wasted motion; to provide means whereby long usage of said device will not result in unimproved opera? tion of the mechanism; and; ,to provide means whereby the frictionally engaged parts are automatically adjusted With respect to each other.

The invention consists in the arrangement of the parts, combination of the elements, and in the details of the construction,

as hereinafter claimed.

In the drawings: Fig. 1 is a rear end elevation of an internal combustion engine showing the inven- 35 tion incorporated therewith 3 Fig. 2 is a section taken on a line corresponding to 22 in Fig. 1;

Fig. 3 is a section taken on a sponding to 33 in Fig. 1; I

In the preferred construction of the invention I provide the usual starting motor 1 having its casing 2 secured, by the bolt 3, to the casing 4 having its lower edge 5 bolted to the lower crank case casing 6 5 which also surrounds the usual fly wheel 7 fixed to the rear end of the usual crank shaft 8 of the internal combustion engine 9.

The shaft 10, of the motor 1, has a plu- O rality of spaced a art V-shape, or ta ered grooves 11, forme eircumferentially t ere line correof, the outer end 12 of the shaft '10 being rotatably mounted inthe casing 4.

Integrally formed inthe' outer circum fer'ential surface 13,- of the fly wheel 7,-are the spaced apart V-shape, or tapered grooves. 55* 14, aligned with the respective groov'es l l." Intermediate the shaft andthe Wheel 7 y is the idler Wheel 15* rotat'ably mounted on the shaft 16 having its ends 17 received through the holes 18', in t'he case 19; W to which are threaded the nutsQO. Around-- the shaft 16 is the bushing" 21? upon which. is mounted the plurality of wheels-eahavin-g' the members 23int'egral With their hub'sl 24: The n embersQS are adapted to' cl'os'ely fit' 6b intothe grooves 11 and? 14, respectively,' into the shaft 10 and the'flywheel 7 Integral with the casing 19"isthe"arm 2 5 slidably mounted in the hole'2 6 in the Gas ing 4; r Slidable upon* the outer end of the arm 35 is the cup 26 having the coiled spring27 therein adapted to force the cup outwardly from the arm. I

Through the arm 'is' thejain'28against" 75 which the 'end'g29 of the coiled spring 30 presses,- having its other end 3f engagingtlie casing 45, whereby the casing 19 is frnce'd inwardly ofthe casing tothe limit of con of the pin 32, received through tlie arm 25, with the casing 4. v Slidably' mounted in the frame 33, suitabl fixed t'o thecasing 4; is the rod 34 hay: ing the projection, 35" adapted to engage the (mp 26; when the rod is" forced inw rdiy asf shown in Fig.3, The spring 36freceived around the rod 84 and engagingithe frame 33 and the head 37, of the rod, normally forces the rod oufiward ly' and disengages the projection from th'e'cup26i y i Fixed to the support 38, fixed to the easing t, is the switch 39 having'theicondiictors' 40 and 41' respectively, leading 'to the termi nal 4E2, of the battery 43am. t he' st ertingq motor. 1. The other terminal 44 Qffiliejbaft tery is grounded to the" casi'ngj 4 o'ffth'e engines; as by theconductor ,451 y The" end 4'6, of the ,rod' 34 isfa'dttpted to"; engage the switch 39; afterrheree ie'ioreed imvenily w'ith" the projection as manage 'V-shape members and the switch 39 when manual inward pressure is released from the head 37 of the rod.

7 The head 37 may be projected from the floor board, or elsewhere, when the device is utilized on an automobile.

An advantage of the invention is that when power is transmitted from the starting motor to the fly wheel the machine is practically noiseless.

- Moreover, the power is transmitted, irrespective of the relative speeds of the starting motor and the fly wheel without likelihood of damaging the mechanism.

Therefore, I have invented a practical and highly desirable device for the purposes intended, and while I believe that the form of the invention illustrated in the drawings and referred to in the above description is the preferred embodiment, and is efiicient and practicable, yet I realize that the conditions under which the device may be operated will necessarily vary, for which reason I desire to emphasize the fact that changes in the details of the construction may be resorted to, when required, without sacrificing any of the advantages of the invention as defined in the claims.

In other words, it is understood that changes and modifications in the embodiment of the invention, such as its size, the materials used and the like the shape of the grooves as disclosed herein, can be made within the scope of with said tapered means in said grooves,

whereby power is transmitted from said input member to said output member, said manual operative means comprising a rod slidably mounted in the casing of said engine and having a projection thereon, an arm connecting with said means having tapered means, said arm being slidably mounted adjacent said engine, a cap on the end of said arm, resilient means intermediate said cap and said arm whereby movement of said rod with said projection and contact with said cap forces said last mentioned tapered means in said grooves.

2. Means for rotating the crank shaft of an internal combustion engine comprising a rotatable power input member having a V- shape groove therein, a rotatable power output member having a V-shape groove therein and operatively connected with said crank shaft, rotatable means having a V-shape member, means to rotate said input member and manually operative means to move said means having a Vshape member in contact with said input member and said output member, with said V-shape member in said grooves, whereby power is transmitted from said input member to said output member, said manual operative means comprising a rod slidably mounted in the casing of said engine and having a projection thereon, an arm connecting with said means having a V-shape member, said arm being slidably mounted adjacent said engine, a cap on the end of said arm,'resilient means intermediate said cap and said arm whereby movement of said rod with said projection and contact withsaid cap forces said last mentioned V-shape member in said grooves.
